Used cervelo R3 56cm with Dura Ace 7900 elements, rotor sub compact crank, and mavic cosmic wheels. I won the body direct from cervelo while my different (and far older) R3 had problems. This body rides and handles like a dream, extremely clean, agile, and lightweight. However this is a bit too large for me. Dura ace shifters and brakes paintings highest and the rotor crank is a beast. The body and wheels have approximately 1,000 miles on them and the remainder of the elements have extra.
